| 英文摘要 | We report the R = alpha(e(+)e(-) --> hadrons)/sigma(e(+)e(-) --> mu(+)mu(-)) for 85 center-of-mass energies between 2 and 5 GeV measured with the upgraded Beijing Spectrometer at the Beijing Electron-Positron Collider. Using the same data sample, we also present the inclusive momentum spectra and multiplicity distribution. These results are compared with both experimental data from high energy e(+)e(-), ep and p (p) over bar experiments and QCD calculations. |
